WINDOW-CLOSING LOCK.

Application filed May 3, 1920. Serial No. 378,378.

T 0 all whom it may concern. Be it known that 1, JOHN Warren, a c1t1-zen of Lithuania, residing at Pittsburgh,

county of Allegheny, and State of Penn 5 sylvania, have invented certainnew and,

useful Improvements in Window-Closing Locks, of which the following is aspecification.

T he present invention relatesto improvements in window sash holders andlocks, and it is the object to provide a device of this kind of greatpracticability and strength and adapted to be cheaply manufactured.

- Another object of the invention is the provision of a device forallowing the loclring of a raised window in any relative position of thesashes. V

A further object of the invention is the provision of a window lock andsash holder of the above character which will possess advantages inpoints of efficiency and durability, and which is simple in constructionand operation.

These objects areattained by the novel construction and combination ofparts hereinafter described and shown inthe accompanying c'lrawingforming a material part of this disclosure, and in which-- Figure l is afront view showing the application of the device constructed accordingto the invention to a window, and

Figure 2 is a side view thereof partly in section.

Referring to the drawing in detail the numeral 10 designates the upper,and 11 the lower frame of a window. Secured to the front face of theupper window frame is a metal plate 12 by means of screws 13 or the likefastening means. This plate is provided at uniformly spaced intervalswith T slots 14. a

A lockmg member 15 of the customary well known constructlon is securedwith its base 16 by means of screws 17 or the like to 1 the upper edgeof lower window frame 11,

and its movable catch provided with the customary handle 19 andlockingmember 2O slides upon a support 21 in the well known manner toengage one or the other of the T slots 14: for locking the window sashesin any relative position to each other. I

While I have shown and described the preferred form of my invention itwill be obvious that various changes in the details.

of construction may be resorted to for successfully carrying myinvention into practice, without sacrificing'any of the novel fea-vtures or departing from the scope of the invention as definedby theappendedclaiin. Having thus described my invention what I claim anddesire to secure by Letters Patent of the United States is y Y A deviceof the character described, corn-g prising in combination with the upperand lower framev of a window, a plate provided with a plurality of Tsockets, screws for securing said plate to the inner front face of theupper window frame, a member secured to the upper edge of the lowerwindow frame and a movable catch adapted to engage with its lockingmember, any one of said sockets for holding and lockingthe window framesin their relative adjusted positions.

In testimony whereof I have affixed my signature.
